A 50 percent increase in salinity of Colorado River water has been projected for the turn of the century—if nothing is done to slow the present rate of increase. In a three-year research project, University researchers from the Department of Land, Air and Water Resources; the Department of Agronomy and Range Science; and Cooperative Extension determined the detrimental agricultural effects of such an increase.

The project was supported by OWRT–U.S. Department of the Interior, California Water Resources Center, and USDA Regional Research Project 129.
